As soon as Docker came out, it was not only financed, but also supported by giants like Google. CoreOS, who had been busy providing technical support for Docker, seemed ready to dip into Docker's light, and now it seems to have another plan: according to GigaOM.com, yesterday CoreOS released a container engine competitive prototype rocket on GitHub, Designed to grab the limelight with Docker.
Rocket is a container engine that is similar to Docker, helping developers to package applications and dependencies into portable containers, simplifying deployment tasks such as environments. CoreOS's CEO, Alex Polvi, said in the official it that Rocket and Docker differ in that Rocket does not have the "friendly features" that Docker offers to corporate users, such as cloud service acceleration tools, cluster systems, and so on. Conversely, what Rocket wants to do is a more purely industry standard.
Alex Polvi believes that CoreOS has decided to launch its own standardised products as Docker seems to have transitioned from beginner's mind, the industry-standard container, to creating a container-centric enterprise service platform.
CoreOS its container called App Containers, which contains app container image, runtime, container-discovery protocol, etc. The app Container image is similar to the image in Docker, and contains the necessary elements for the application, such as source code and binaries. The Rocket runtime is built in accordance with the APP Container standard specifications and is designed to turn the container into a command-line tool.
Polvi says Docker is fundamentally flawed in terms of security and composable, and Rocket's design prototypes are designed to compensate for these flaws.
In fact, Docker has been focused on security in several recent releases, but it's normal for a tool designed to accommodate large-scale enterprise applications.
CoreOS co-founder and CTO Brandon Philips is currently a member of the Dcoker Management Committee and CoreOS intends to continue to support the Docker project, but when Rocket matures, they will reassess whether to continue to contribute.
After CoreOS's official blog post, Docker Ben Golub wrote a blog post, saying, "Although we disagree with some of the ideas and rhetoric in CoreOS's article, we hope that we can move forward in the direction of making the real ultimate product for developers and users." ”
